Banksia armata var. armata is a variety of shrub endemic to Western Australia.

Description

B. armata var. armata grows as a spreading shrub, up to three metres in height, with deeply serrated leaves and a bright yellow inflorescence.[1][2][3]

Distribution and habitat

It occurs throughout much of the south-west. The main distribution is between Perth and Albany, but it also occurs near Mount Lesueur in the north. It grows amongst open woodland or heath, on rocky soils.[3][4]

Taxonomy

Specimens of B. armata were first collected at King George Sound in December 1801 by Robert Brown. Brown published a description of the species in 1810, naming it Dryandra armata; the specific epithet is from the Latin armatus ("armed") in reference to the sharply serrated leaves. Thirty years later, John Lindley published a purported new species, which he named Dryandra favosa.[5] This was accepted as a species by Carl Meissner in 1845,[6] but declared a taxonomic synonym of D. armata by him in 1856,[7] and the latter view was taken by George Bentham his 1870 Flora Australiensis.[8] In 1996, Alex George published D. armata var. ignicida, thereby invoking the autonym D. armata var.armata. George also refined the synonymy of D. favosa to this subspecies.[1] In 2007, all Dryandra species were transferred to Banksia by Austin Mast and Kevin Thiele;[9] hence the current name of this variety is Banksia armata (R.Br.) A.R.Mast & K.R.Thiele var. armata.[10]
